Plasmaviridae


More information.


Classification and Host Range

  • Family: Plasmaviridae
  • Host Range: Primarily infects Acholeplasma species, members of the Mollicutes class.
  • Taxonomy: Contains a single genus, Plasmavirus, with only one recognized species: Acholeplasma virus L2.
  • Limited Knowledge: This family is poorly studied, with limited information available regarding diversity and biological characteristics.


Genome Characteristics

  • Genome Type: Single-stranded, circular, supercoiled DNA molecule.
  • Genome Size: Approximately 12 kilobase pairs.
  • G-C Content: Relatively high at around 32%.
  • Gene Content: Contains 14 open reading frames, encoding at least 15 proteins, including at least four structural proteins embedded in the viral membrane.


Virion Structure

  • Morphology: Quasi-spherical to slightly pleomorphic.
  • Size: Approximately 80 nm in diameter (range 50-125 nm).
  • Envelope: Enveloped virions.
  • Symmetry: Undefined.
  • Genomic Arrangement: Circular.
  • Genomic Segmentation: Monopartite (single-stranded genome).
